Feature Request: CD Music Support #21

Open vicokoby opened 2 months ago

vicokoby commented 2 months ago

There are many games that use CD music, such as Rayman 1, Fatal Racing, Screamer 2, and many more. Is it possible to implement support for this?

I guess the games expected the CD device to be connected to the sound card; then they could simply emit a "play" command and the sound card would then have mixed the (analog) CD audio signal with the game's SFX output.

I'm afraid to emulate this purely in software would require a lot of CPU resources - probably only doable by running 2 cores; not exactly trivial to implement.

I understand that through a 4-pin analog cable like the one in the attached image, the sound is provided by the hardware. Wouldn't an implementation for this be more feasible? 347028

Sorry, don't know this thing. How exactly is it supposed to be attached? I'd rather expected some SPDIF proposal.

This video shows how to connect the cable between the sound card and the CD player. Sorry it is in Spanish https://youtu.be/-yLAI4b2QKs?si=84qxQ3gSTpvDa8AZ
